Rockliff was rotated between the midfield and forward line last season but has trained exclusively in the midfield this pre-season.

The former All-Australian hopes to recapture his best form after struggling to assert himself in his first season with Port.

"Probably I was a little bit tentative at times last year because I didn't want to step on the boys' toes," he said.

"I feel like we're in a much better position to give it a fair dinkum crack this year and I feel like I'm in a much better position being in the system for 12 months, knowing the boys but also (having) confidence in the body."

Port, who finished a disappointing 2018 season in 10th place, will soon unveil their new captain to replace veteran Travis Boak.

Young gun Ollie Wines is favourite to take the reins but the Power could appoint co-captains, with fullback Tom Jonas another leadership contender.

Rockliff added defender Hamish Hartlett was close to returning to full training after tearing his ACL last season.

The Power will monitor the fitness of star forward Robbie Gray, who has been withdrawn from the AFLX exhibition after reporting knee soreness.
